What is a Filter Circuit ?

Generally, a rectifier is required to produce pure d.c. supply for using at various places in the electronic circuits. However,

A transistor raises the strength of a weak signal and thus acts as an amplifier. The Below Fig shows the basic circuit

The emitter-base junction of a transistor is forward biased whereas collector-base junction is reverse biased. If for a moment, we

A transistor consists of two pn junctions formed by *sandwiching either p-type or n-type semicon-ductor between a pair of opposite

The below Figure shows a bias arrangement for both npn and pnp BJTs for operation as an amplifier. Notice that in

The basic structure of the bipolar junction transistor (BJT) determines its operating characteristics. The BJT is constructed with three doped

The pin diode consists of heavily doped p and n regions separated by an intrinsic (i) region, as shown in Figure

A tunnel diode or Esaki diode is a type of semiconductor that is capable of very fast operation, well into
